Great job explaining EROI in this video shared by @shonin. A Very Smart Person sums it up this way, “…I think The Environment is Fucked…”.
Thank you to @shonin for sharing!

As a follow up, a nice critical article on point of view, with a particular focus on EROI claims, intermittency, and so on.

I haven't seen much yet on the fediverse featuring the work of Mr. Hagens, but I usually enjoy his podcast and guests. He recently did a great ~20 minute short on energy return on energy investment, I found it quite enjoyable. He delves into the challenges and weaknesses of some of the different approaches for measurement, and the show notes are packed with some great references and links as well! Beware, this one is quite dense as far as videos go!

That's one side of the argument - You have provided information on the low concentration of uranium in some ore projects.

The other side of the argument is the incredible energy density of uranium. Natural Gas has the highest energy density of common fuels at 55 Mj/kg. The energy density of U235 is 3,900,00 Mj/kg. Source: energyeducation.ca/encyclopedi

For this reason, nuclear power provides a high Energy Return Over Investment ratio of around 100.

There are no solutions only trade-offs.

This meme is provided by Generation Atomic.

Yes, there is a leak, but tritium is not an especially dangerous isotope at these concentrations.

We see here a bug with nuclear power when serious pollution and CO2 emissions are a feature of all fossil fuels.

A significant concern of mine is that we need to use high Energy Return on Investment sources of power. EROI of different sources of energy are: /1

#200 in viaggio verso Firenze per il secondo appuntamento tema nuvole e meteorologia. Sottopasso alla stazione di Bologna, all'improvviso mi appare di fronte un'eroina: maestra sola - in quel momento - con una truppa di una ventina di personcine piccole, silenziose, ordinate, vicino al muro.

Non tutti gli eroi portano il mantello e non tutti li meritiamo.

Finally, I'm confident that the superior of nuclear will gradually lead to the replacement of and That's a long way of saying that, IMO, and will co-exist. 2/end

Why sustainable power looked unsustainable in 2009? Still true? (me: of course it is, IF one wants the SAME society/economy of 2009) newscientist.com/article/dn165

, , , ...? Da hat sich die Heise Redaktion die low-hanging-fruit angeblicher Gegenargumente heraus gepickt. Quasi Strohmänner aufgestellt.

Wichtiger wäre folgende Frage gewesen: Skaliert eine weltweite (!) Versorgung mit PV und Windstrom? Also: gibt es dafür genügend von allen (!) benötigten endlichen Rohstoffen?

Denn sonst wäre PV & Wind womöglich nur die gutes-Gewissen-Erzeugung für die westliche Welt weil es für den Rest nicht reicht.
